An efficient and rapid procedure for synthesizing S‐linked glycopeptides is reported. The approach uses activated molecular sieves as a base to promote the selective S‐alkylation of readily prepared cysteine‐containing peptides, upon reaction of appropriate glycosyl halides. Considering the very mild conditions employed, the chemoselective linkage of the electrophilic sugar with a peptide sulfhydryl
